[The silent sinus syndrome: A reconstruction of the orbital floor with Medpor implant].

Introduction: The silent sinus syndrome (SSS) is a rare clinical entity in both ENT and ophthalmology. It is characterized by enophthalmos and ptosis associated with a reduction in pressure in the maxillary sinus caused by chronic hypoventilation. The objective of this study was to demonstrate the importance of maxillary hypoplasia whether congenital or acquired in this disease, and the use of Medpor implant for reconstruction of the orbital floor.

Material And Methods: We report 3 cases of silent sinus syndrome proved clinically and radiologically. The first is a 45 year old male patient complaining of enophthalmos which occurred gradually, without any medical history; the second case is that of a woman of 39 years with a gradual onset enophthalmos, with a history of sinusitis; the third case, a man of 25 years who had a history of nasal trauma and consults for enophthalmos and diplopia.

Results: Endoscopic surgery is performed quickly allowing a disappearance of enophthalmos and diplopia. All patients underwent a reconstruction of the orbital floor with a Medpor implant fixed by miniplates without complications.
